The loader 39 is moved to the left until it contacts the stock sheet W from stock 5 and the support table 43, and then the suction cups 41 are lowered to absorb and raise the stock sheet W to a predetermined height. The loader 39 is then moved to the right of the turret piercing tree 5 to the cradle 1, and the suction cups 41 are lowered and removed to allow the material plate W to reach the press 1.

As shown in Figures 1 and 2, the turret punch press or shear machine 1 has upper and lower bodies 45 and 47, by means of which the upper and lower rollers 49 and 51 are rotatably supported. A plurality of piercers PN and a compatible pad 10 D are disposed within the peripheral area of the revolvers 49 and 51. The punch 53 is mounted above the upper body 49 revolvers 49, 51 and is actuated by actuators (not shown) by hitting the piercer PN at the piercing position 55. The revolvers 49, 51 are rotatable to position the PN punch pad D of the desired piercer at the piercing position 55 and just below.

15 The center table 57 is secured in front of the piercing point 55, and the front side table 59 and the transport table 61 are disposed on the left and right sides of the center table 57. The trolley base 63 is mounted over the front ends of the front side table 59 and the conveyor table 61 so that the trolley base 63 and the two tables 59, 61 are integrated as a frame. The tables 59, 61 move integrally with the trolley base 63 20 in the Y direction along at least one guide rail 91 (Fig. 6) disposed beneath the tables 59, 61 and parallel to the Y. The carriage 65 having the clips 67 is mounted on the carriage 63 for moving in the X direction.

; ; ': The material sheet W from the loading device 3 is gripped at its front by the retainers 67 and is moved several times in x, y by moving J 25 tables 59, 61 with trolley base 63 or trolley 65 from plate W to insert the required parts of the punch PN and cushion D at the puncture point 55. The press device 69 disposed on the left side of the press 1 presses the disc W and the cutting device 71 on the right side of the press holds the disc in place during punching of the turret punch press 1.

• · o 30 Tables 59, 61 and trolley 65 are operated by actuators (not shown), such as motors, screws, etc. Detailed descriptions of gripping the plate W supplied by the loading device 3, movement of tables 59, 61 Y: nr. cc) ... in the direction of f and moving the carriage 65 and the clips 67 in the direction of X have been omitted here because they are well known.

35 Removing the small articles G from the work plate W is performed at position 73 adjacent to the press 1 by using a cutting device 71 shown in detail in FIG. 7 105897. The work piece W held by the clips 67 is suitably moved in X and Y following punching by the press 1 so that the alternately.

In Fig. 4, the cutting device 71 is mounted on the press 1, for example 5 on the upper and lower frames 45 and 47 of the press 1. The stamp holder 75 is supported on the upper frame 45, while the cushion holder 89 is supported on the lower body 47.

The hollow cylinder 79 is supported to move vertically into the die holder 75 via a low stiffness helical spring 77 disposed therein. The hollow cylinder 79 penetrates through the bottom of the die holder 75. An opening 80 is formed in the bottom portion of the hollow cylinder 10 79. The fluid cylinder 85 is also supported on the upper body 45. The fluid cylinder 85 has a piston rod and a punch 83 is supported on the free end of the piston rod. The die 83 has a point 84 and is guided to the hollow cylinder 79. The high rigid helical spring 81 is disposed between the die 83 and the hollow cylinder 79.

On the other hand, the cushion 87 is supported on the cushion holder 89 and an aperture 88 is formed in the cushion 87. The aperture 88 extends into the hole of the cushion holder 89.

Accordingly, the low stiffness spring 77 first shrinks when the low pressure fluid is supplied to the fluid cylinder 85 and the hollow cylinder 79 presses the work plate W against the die 87. The uncut part A, B, C, D, E, F, 20 H or K is below the hole 80. The fluid pressure in the cylinder 85 then increases and therefore the punch 83 drops due to the pressure while the high-rigid helical spring 81 shrinks. The punch tip 84 passes through the hole 80 and presses the uncut part i, A, B, C, D, E, F, H or K, which then drops into the hole 88 of the pad 87.

The guide rail 91 is supported on the lower frame 47. The slide 93 is mounted on the guide rail 91 so that it slides along the Y-direction guide rail 91. The two V ·: frame members 95A and 95B, which are parallel to X, are spaced apart and 105897 8 are mounted on slides 93, and the body members 97 are in Y direction and form a bridge between the body members 95A and 95B, and are spaced apart in the X direction. Rollers 99 are disposed between body members 97. Both ends of each roll 99 are supported on body members 95A and 95B for rotation.

A plurality of guide rollers 101 are disposed below the front ends of the rollers 99 and are rotatably supported on the body 95A. The fluid cylinder 103 is disposed beneath the guide rollers 101 and the motor 107 is mounted on the fluid cylinder 103 via a support 105. The support 105 moves with the motor 107 along two rails 109 which are vertically aligned with the actuation of the fluid cylinder 103. The drive wheel 10 is connected to the drive shaft of the motor 107 and the impeller 113 is disposed around the wheel 111 and the guide rollers 101 and under the rollers 99. The guide rollers 101 use a convexity to concentrate the force on the center of the belt 113 so that the belt 113 is prevented from bending and to allow the belt to run smoothly.

To convey the small pieces of product G, the cylinder 103 is first actuated to lower the engine 107 along the guide rails 109. As a result, the belt 113 is tightened. The motor 107 is then driven and the rollers 99 rotate clockwise, moving the articles G to the right.

When detaching small pieces of product G from the work plate W at the cut-off point 73, the rollers 99 rotate. Therefore, the small pieces of product G rapidly exit from 20 tables 61 to auxiliary table 7 before the next piece is removed. The auxiliary table 7 is similar in structure to the conveyor table 61. The path of product G from the conveyor table 61 to the auxiliary table 7 is shown in Figure 2 with large arrows.

When the working plate W is forced to puncture the press 1 at 55, the fluid cylinders 121 are actuated and the supporting bases 117 raised to support the plate W in portions by the support rollers 115. Therefore, the plate W is prevented from moving and vibrating. The linear sleeves 123 prevent the support rolls 115 from vibrating when the punch press 1 is in operation and also hold the rollers 115 in a predetermined position.

When the small pieces of product G are conveyed to the conveyor table 61, the support rolls 115 are lowered and the pieces of product G rest on the rollers 99 and are removed from the table 61.

Figures 7 to 9 illustrate small article conveyors 9. The small articles G enter the device 9 from an auxiliary table 7. The devices 9 comprise a frame structure 125 on which a plurality of tubular rollers 127 are mounted rotatably. The tubular rollers 127 disposed X are spaced apart. and gradually decrease as you move to the right (Figure 8). So. the roll 15 on the right is lower than the roll on the left. The frame structure 125 is supported by a motor 129 for rotating the rollers 127. The pulley 131 is connected to the drive shaft of the motor 129.

Steering wheels 133R, 133L are rotatably disposed at both ends of body 125 (Fig. 8). In addition, a plurality of guide wheels 135 are rotatably disposed between tube rollers 127. The endless friction belt 137 is disposed around the pulley 131 and the guide wheels 133R, 133L. The belt 137 is guided by the guide wheels 133R,; j '133L between the upper surfaces and the lower surfaces of the tubular rollers 127 and is in contact with the surfaces; •; * in the chains so that friction is exerted between the belt 137 and the surfaces.

Referring now to Figures 1, 2, and 10, the automatic store 13 comprises a ... frame structure. The structure and function of the automatic warehouse 13 is almost identical to that of the automatic warehouse 5 by transporting the pallet P by the lifting device 19 to the receiving device 17, which is located in the upper part of the frame structure 15. Therefore, the same reference numerals and letters are used to denote i ·· the same structural and functional elements, and the description of the elements has been omitted here. Only the different points are explained here.

In Figure 10, the automatic warehouse 13 comprises a sorting device 11a a for collecting and sorting small pieces of product G placed on the conveyor device 9. The sorting device 11 has at least one guide rail 177 mounted in the frame structure 15 and oriented in the X direction. The guide rail 177 is fixed to 11105897 by a rack 179 parallel to the X. The carriage 183 is supported by a guide rail 177 via a gear 181 disposed in the carriage 183 and engages a gear rack 179. The gear 181 is rotated by an engine 185 mounted on the carriage 183. Engine 185 is preferably a servo motor and an encoder.

5 The carriage 183 moves along the guide rail 177 while the engine 185 is running. Liquid cylinder 187 with piston rods 189 is secured to carriage 183. The lower end of piston rods 189 is secured to a Y-direction pull bar 191 having a plurality of clips 193. The clamps 193 are moved vertically when cylinder 187 is actuated.

10 The motor 185 is operated and the clips 193 are moved to the left to the small pieces G of the conveyor 9. Then, some holders 193 are activated to engage the bodies G and then moved to the right. A portion of each piece G (shown in dashed lines in Fig. 10) is supported on the slats of an operating lamella conveyor 27. The clips 193 are stopped at a predetermined position above the lifting device 19 while the lamella conveyor 27 is operated sequentially so that the slats 33 are removed from the lifting device 19. The position of the holders 193 is indicated by an encoder attached to the motor 183. The clips 193 are then lowered by actuating the cylinder 187 and the pieces G are placed on the pallet P.

When many pieces G are stacked on pallet P, the pallet is removed by crane 21 (not shown) and transported to the receiving device 17.

As can be seen from the description above, the pieces G are automatically placed according to their quality on the pallet P. The positions can be changed by controlling and observing with encoders both the amount of displacement of piece G in direction Y on conveyor 9 and the amount of displacement of carriage 183 in direction.

In the present invention, the processes from importing material plates W to sorting a plurality of product pieces G cut from plates W are automatically performed, and pieces G are sorted according to different grades. In addition, the product pieces G are stacked on a pallet and consequently the product storage space is reduced.

The present invention is not limited to the embodiment described above and may be embodied in modified embodiments. For example, the cutting device 71 can be detached from the turret punch press 1 and mounted independently on the floor. Instead of a turret punch press, the La machine can be used to form a plurality of small pieces G of the work plate W Meis.
